Anti-lock brake warning
This light together with and indi-
cates that a fault has occurred in the ABS
system. Conventional braking without the
ABS function will still be available.
For safety reasons, stop the car and check
the level of the brake fluid (see page 175).
If the level is normal, depress the brake
pedal firmly two or three times. Now check
the level again. If the level is still normal, you
may drive the car, with considerable cau-
tion, to the nearest authorized Saab dealer
to have the brake system checked.

Airbag warning light
This light together with will come on if
a potentially serious fault has occurred in
the airbag system.
The light will come on for about three sec-
onds when the ignition switch is turned to
the Start or Drive position. It should go out
after the engine has started.
CHECK message indicator
This light indicates that there is a message
in the SID. A chime will also sound
(see page 58).
Central warning light
This light will come on and a chime will
sound if a fault has been detected in any
system that is critical to safety. Any of the
following can activate the central warning
light and alarm:
 Airbag system.
 Low oil pressure in engine.
 Parking brake is on (when car is moving).
 Brake fluid level low.
 Fault detected in ABS system.
 Engine overheating.
 Alternator not charging properly.
The symbol and audible alarm are also acti-
vated if the ignition key is turned to the ON
position and the engine is not started within
10 seconds.
WARNING
 If the ABS is inoperative, there is a
danger of the rear wheels locking up
on hard braking.
 If the level of brake fluid in the reser-
voir is below the MIN mark, the car
should be towed to an authorized
Saab dealer.
WARNING
 If the airbag readiness light stays on
after you start your vehicle, it means
the airbag system may not be working
properly.
 The airbags in your vehicle may not
inflate in a crash, or they could even
inflate without a crash.

Engine malfunction
This light indicates a malfunction in the
fuel-injection or ignition system. The car
may still be driven with care and with some-
what diminished performance (see page
132).
Indicator, fuel
This light comes on when there is less than
about 2.5 gallons (10 liters) of fuel left in the
tank.
Indicator, cruise control
This light shows when the cruise-control
system is active (see page 145).
Indicator, high beam
This light shows when the headlights are on
high beam (see page 61).
Indicator, rear fog light
This light shows when the rear fog light is on
(see page 62).
The rear fog light is switched off automat-
ically when the engine is switched off. When
the fog light is next needed, it will have to be
switched on manually again.
The rear fog light consists of one light so it
should not be mistaken for rear light.
Indicator, open door
If a door has not been closed properly, the
pictogram will indicate the door concerned
(or tailgate).
WARNING
An illuminated “Engine malfunction” indi-
cator light indicates a serious
engine-related problem. While your car
may be able to be driven with the “Engine
malfunction” indicator light illuminated
(Limp-home mode), you are advised to
have your car serviced at a qualified facil-
ity as soon as possible.
Continued driving without this problem
being corrected might cause serious fur-
ther damage to your car and create
unsafe driving conditions. The operator
should be prepared to take action if such
unsafe conditions arise (e.g., apply the
brakes, disengage transmission, turn off
the ignition etc.).
NOTEIf the car runs out of fuel, air can have
been drawn in with the fuel, which, in turn,
can cause the catalytic converter to be
damaged by overheating.

134 Starting and drivingTo ensure that the catalytic converter con-
tinues to function properly, and also to avoid
damage to the converter and its associated
components, the following points must be
observed:
 Have the car serviced regularly in accor-
dance with the service program. The fuel
and ignition systems are particularly
important in this context.
 Always be alert to any misfiring of the
engine (not running on all cylinders) and
any loss of power or performance. At the
first sign of a malfunction, reduce speed
and take the car to an authorized Saab
dealer as soon as possible.
 If the engine fails to start (in very cold
weather or if the battery is flat), the car can
be jump started (manual gearbox only) or
started using jump leads to a donor bat-
tery. However, as soon as you have
started the engine, it is important that it
runs on all cylinders. If it is misfiring, allow
i t t o i d l e f o r u p t o f i v e m i n u t e s t o g i v e i t t i m e
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
turn off the engine and get in touch with an
authorized Saab dealer for advice.  Never park the car on dry grass or other
combustible material. The catalytic con-
verter gets very hot and could therefore
start a fire.
 Never drive off if the engine is misfiring.
 If you jump start the car when the engine
is already up to normal temperature, the
engine must start to run on all cylinders.
Stop jump-starting if the engine fails to
start immediately.
Failure to follow these directions could
result in the catalytic converter and associ-
ated components being damaged, and
could represent a breach of the warranty
conditions.
V6 engine: When starting the engine from
cold an electrical pump is activated. This
pump pumps air into the exhaust system so
that the catalytic converter will reach its
normal operating temperature more rapidly.
The pump is active for 30-60 seconds.
RefuelingAlways use the correct grade of fuel:
unleaded AON 87-93.
Saab recommends:
 AON 90 for 4-cylinder engines
 AON 93 for V6-engines and 2.3 Aero,
(see page 228).
If fuel containing a mixture of alcohol is
used, the following restrictions apply:
Methanol: max. 5% by volume.
Ethanol: max. 10% by volume.
MTBE: max. 15% by volume.
The fuel filler cap is located in the right rear
quarter panel.
Switch off engine.
Open fuel door
Insert the fuel-pump nozzle beyond the
flange on the filler pipe. Do not withdraw the
nozzle while filling is in progress.
Cease refuelling the first time the pump
stops.
Fuel-tank capacity: 18.5 US gal. (70 liters)
Screw on the filler cap and keep turning until
it has clicked at least three times.
The most effective way to prevent conden-
sation forming in the tank (and thus avoid
NOTEIf the car runs out of fuel, it is possible for
air to get into the fuel system. If this
happens, the catalytic converter may
overheat and be damaged.
NOTEDo not overfill. Fuel should not come right
up the filler pipe as expansion room is
needed.

141 Starting and driving
Overheated transmission fluid If the automatic-transmission fluid should
overheat, the following message will appear
on the SID:
”TRANSMISSION OVERHEATING”. If this
happens, stop the car and wait for the mes-
sage to be extinguished. Continue driving in
a locked gear that produces an engine
speed of about 3,000 rpm.
Overheating of the automatic-transmission
fluid can occur when the car is towing a
heavy load, such as a camping trailer in hilly
country, with the wrong gear selected,
resulting in abnormally frequent gear
changing. Try selecting position 1, 2 or 3.
High ambient temperatures can also
increase the temperature of the transmis-
sion fluid or the oil cooler may be faulty.
Contact an authorized Saab dealer (see
also page 152).
Towing Towing of cars with automatic transmission,
see page 158.
NOTEIf the control module has actuated the
Limp-home function for the automatic
transmission, the car will remain in 4th
gear when D is selected, making it very
sluggish. To overcome this, move the
selector lever to position 2.
WARNING
Remember to use engine-braking (selec-
tor position 1, 2, or 3) to spare the brakes
when you are driving on a long or steep
downhill slope. Select the same gear as
you would on the corresponding uphill
slope.
Brake failure can result from overheated
brakes!
ProCarManuals.com

143 Starting and driving
If the gear selector lever is moved from position D to 1, a
change-down to 3rd gear will occur at about 110 mph (180 km/h).
A change-down to 2nd gear will occur at about 75 mph (120 km/h)
and to 1st gear at about 40 mph (65 km/h).
When position 1 is selected, all the other gears will be locked out.
Manual gear-changing is not recommended on slippery roads.
Adaptive gear-change patternsAdaptive gear-change patterns are selected automatically depend-
ing on the engine load and the present temperature of the transmis-
sion. The function is available in Normal and Sport modes.
The changes occur at a higher engine speed and the car remains in
the same gear for longer, if the transmission control module senses
that the load has not decreased. These gear-change patterns pre-
vent unnecessary changing up and down, when for example driving
up long slopes with a trailer or caravan, and to prevent overheating
the transmission oil. The adaptive gear-change function is also
selected automatically when the transmission oil becomes too hot,
to protect the transmission itself from serious damage and to lower
the oil temperature.
The adaptive gear-change pattern function is deselected when:
 Winter mode is selected.
 The engine is switched off.
 The load is reduced so much that the function is no longer
required.
 “Fault indicator, automatic transmission” appears on main
instrument panel, see page 140. 1
Position 1 should be used when maximum
engine-braking is required on steep downhill
slopes and to avoid frequent gear-changing on
steep climbs.
Do not move the selector to position 1 at speeds
in excess of 37 mph (60 km/h).

144 Starting and drivingSPORT and WINTER modes
To select Sport mode, press the ”S” button on
the selector lever when the selector lever is in
position N, D, 3, 2 or 1.
In this mode, gear changes will take place at
higher engine speeds than in Normal mode, in
other words, the transmission will change up
later and change down earlier for the same throt-
tle (accelerator) position.
The Sport mode will be deselected if:
 The S button is pressed.
 The selector lever is moved to position P or R.
 The engine is switched off.
 The Winter mode is selected.
 “Fault indicator, automatic transmission”
appears on main instrument panel, see page
140.
The Winter mode facilitates pulling away and
driving on icy roads. Third gear is selected auto-
matically for pulling away to reduce wheelspin.
Winter mode can be selected when the engine
is running by pressing the ”W” button on the
selector-lever surround. It cannot be selected
when the selector lever is in position 2 or 1.
Note: It is still possible to use kick-down in the
Winter mode, in which case a change-down to
1st or 2nd will take place.
The Winter mode will be deselected if:
 The W button is pressed.
 The engine is switched off.
 The selector lever is moved to position 2 or 1.
 Kick-down is activated.
 The automatic-transmission fluid overheats.
